Another new problem for me since this last upgrade - for some recipients, Airdroid has decided to send their texts off to their landline # rather than the mobile # even when the latter is set as Default. Got me into a bit of trouble over a parcel that was posted that shouldn't have been but I thought the recipient was just too busy to reply when she actually hadn't received any of the 3 texts sent. This applies only to those already in my contact list obviously. Has happened on 4 occasions before I discovered the problem.
